Latest Review Posted | SMC Pentax-M 24-35mm F3.5 My impressions after doing tests with this lens, and also carrying it as a daily shooter are conflicting. It performs horribly in tests, but I love using it and all it's characteristics. There is fringing at all focal lengths until f/8, there is mild-moderate barrel distortion at all times, there is heavy vignetting wide open. But there's just something about it that keeps it on my camera. It has very mild bokeh-swirling. I like the vignetting because I add a little to my images anyway, I like the mild softness even when focus is nailed because it's flattering, and I like the mild distortion because it takes a while to fall off the edges.
This difference between f/3.5 and f/4 is crazy. It's like 6 primes in 1, instead of 3 primes in one, because of that difference. At f/3.5 the lens's bokeh falls off similar to Cookes.
My 24, 28, and 35mm primes all destroy this lens in image quality, but I can't carry all of them all the time, and they don't have the character this lens does. Very interesting. I will endeavor to shoot a short video project with this lens and see how it does.
